Bow with arrow rest



Sept. 5, 1961 A. & SACKMANN BOW WITH ARROW REST Filed June 4, 1959 IN VE N TO R AUGUST KSACKMANN ATTORNEY.

United States Patent '0 2,998,811 BOW WITH ARROW REST August E. Sackmann, 291 Willis St., Bristol, Conn. Filed June 4, 1959, Ser. No. 818,176 2 Claims. (Cl. 124-24) This invention relates to a bow having an arrow rest and more particularly, to a rest having means provided thereon to reduce the friction between bow and arrow.

Although bows in the past have been provided with rests to support the arrow to be shot and such rests have incorporated means to reduce friction between how and arrow, the prior devices, for various reasons, have failed to reduce the principle to a really practical and efficient embodiment.

It is therefore amongst the primary objects of the present invention to provide a truly practical and eflicient arrow rest of the type incorporating friction reducing means.

It is another important object of the present invention to provide an arrow rest of the above stated class which is detachably atfixed to the bow.

It is yet a further object of the present invention to provide an arrow rest of the above stated class wherein the housing for the friction reducing means permits said means to be easily maintained at optimum operating efficiency at all times.

These and other objects are accomplished and new results obtained as will be apparent from the devices described in the following specification, particularly pointed out in the claims, and illustrated in the accompanying drawings in which:

FIG. 1 is a side elevation of a bow, with its ends broken away, showing an embodiment of the device of the present invention; 4

FIG. 2 is a sectional view taken on lines 2-2 of FIG. 1, in the direction of the arrows;

FIG. 3 is again a broken away side elevation of a bow in accordance with the present invention showing another embodiment thereof; and

FIG. 4 is a sectional view taken on lines 4-4 of FIG. 3, in the direction of the arrows.

A11 embodiment of a bow in accordance with the present invention is shown in FIG. 1 consisting of the bow proper, designated generally by numeral .10, and an arrow rest, designated generally by numeral 12.

Rest 12 is positioned at one side of the bow, as indicated, and may consist, as is clearly shown in FIGS. 2 and 4, of a support 14 housing bearing 16 upon which arrow 18 is adapted to ride prior to free flight. It is to be noted that plastic tape may be applied to the bow and in addition to bearing 16, arrow 18 will also contact and ride upon the taped surface of bow 10.

Bearing 16 is removably housed in chamber 20 of support 14 and is freely rotatable therein. The arcuate wall 22 of chamber 20 encompasses most of bearing 16 leaving only a small portion thereof extending from the chamber to provide a freely rotatable bearing surface for arrow 18. A support in accordance with one embodiment of the present invention is preferably of a resilient plastic composition so that the wall 22 of chamber 26 may be readily flexed, for reasons hereinafter appearing. Nylon has been found to be a desirable composition in this connection.

It may thus be seen that removable bearing 16 is normally securely retained in chamber 20 by reason of the curved chamber wall. It has been found desirable, however, to provide for the ready removal of the bearing so that a lubricant 26a may be periodically introduced into chamber 20 and to permit the periodic cleaning of said chamber. A silicone dry powder wax or graphite has been found to be a particularly good lubricant.

A linear access passage 24 is provided within support 14 communicating atone end with chamber 20 and at the other end with the atmosphere. Upon inserting an ejection rod (not shown) within passage 24 and thereafter bringing pressure to bear upon the portion of bearing 16 which happens to be adjacent passage 24 at that time, a force is exerted upon resilient Wall 22 by bearing 16 causing said wall to yield and permitting the release of bearing 16 from chamber 20.

Arrow rest 12 is preferably adhered to how 10 by means of a suitable cement or adhesive which, while reliably holding the arrow rest firmly in position on the bow under actual working conditions, permits the rest to be readily detached from the bow when sufficient manual pressure is brought to bear upon it.

It may be seen that several ways are provided for the mounting of the arrow rest. In the embodiment of FIGS. 1 and 2, the rest merely extends outwardly from a vertically extending side surface of the body of the bow. In the embodiment of FIGS. 3 and 4, a so-called open window arrangement is provided. This permits the rest to be mounted on a normally horizontal working support rather than a normally vertical working support as in FIGS. 1 and 2. It has been found advantageous to maintain bearing 16'inclined with respect to bow 10, as is shown in FIG. 2.

It will be seen that the arrow rest is provided with a fiat, horizontal base surface 12a for mounting on horizontal shoulder 10a of the bow, and with a flat faced vertically extending arm 12b for abutment against vertical wall 1% of the bow. Said vertical arm 12b also functions as a side bearing for the arrow.

Although the invention has been described in detail with respect to preferred embodiments thereof, it will be understood by those skilled in the art, after reading this specification, that various changes and modifications may be made without departing from the spirit of the invention and the scope of the appended claims.

The arrow rest above described is made preferably of molded plastics and that is how it is shown in the drawing. However this is purely a matter of preference and it will be understood that the arrow rest may be made of other materials such as forged or cast metal, preferably aluminum, magnesium or brass. The metal arrow rest would also be attached to the how by means of a cement or adhesive. This method of attachment is also a matter of preference since the arrow rest may be secured by other conventional means such as metal fasteners, tape or the like.

In FIG. 2 the ball bearing is shown mounted in chamber 20, in direct contact with the walls of said chamber. FIG. 4 shows another method of mounting the ball bearing. It will be noted that a metal disc 50 is disposed against the side wall of said chamber. Both the disc and the split ring 52 are made, preferably, of .003 of an inch shim stock, brass, stainless steel or any other suitable metal. When the ball is pressed down upon disc 50 it tends to depress it into a generally dished shape. The lubricant would be placed between the bow on the one hand and said disc and split ring on the other hand. It will thus be understood that said disc and said split ring function as bearing surfaces relative to the ball bearing.

What is claimed as new and desired to be secured by Letters Patent is:

1. In combination with a bow, an arrow rest mounted on said bow and adapted to support an arrow, said arrow rest comprising a housing, having a bottom wall which is adapted to be secured to a horizontal portion ball bearing projecting outwardly from said socket and serving as the bearing surface for an arrow, said vertical portion of the housing being provided with a vertically extending bearing surface for the arrow, said ball bearing surface and said vertically extending bearing surface 00- 5 operating to support and guide the arrow.

2. The combination of claim 1, wherein a metal disc is provided on the floor of said socket and a metal ring is provided against the side wall of said socket, said disc and said ring being adapted to serve as bearing surfaces 10 relative to the ball bearing.
